You forget the greatest of them all - Jimmy Wilde, the "Ghost with a hammer in his hand".

World flyweight champ from 1916 to 1923. he lost 4 out 149 recorded fights plus fought thousands of booth matches in addition. The Mighty Atom is undoubtedly the greatest flyweight of all time (none of the others above could legitimitely claim that in their weight divisions)
